Review on ABN 4x5 Inch Silicone Heater Pad – Engine Block, Car Battery, Oil Pan Heater Pad, 120V 250 Watt: Efficient Heating Solution by Corey Evans

It was easy to install and works great. I put it on a 6 cylinder 3.0 liter BMW E90. I also connected it to an Alexa plug so I can ask Alexa to warm up the car for an hour or two before I have to drive in the winter. Engine at temp. Now it immediately takes on operating temperature. Gas mileage is +5mpg up for short trips, cam ticking is gone and the heater heats up much quicker.
